Job Description - Linux Infrastructure Engineer

Linux Infrastructure Engineer

Location: Charleston, SC

Direct-Hire & Full-Time

Growth Potential, Great Benefits & 401K

We are seeking an experienced Linux Infrastructure Engineer to design, build, and support secure infrastructure across laboratory, R&D, development, and production environments.

This hands-on role combines Red Hat Enterprise Linux (RHEL), virtualization, Cisco networking, OpenShift/container technologies, automation, and air-gapped infrastructure. The ideal candidate will have experience building and troubleshooting infrastructure—not simply performing routine systems administration.

Required Qualifications:

3+ years of experience in Linux systems, infrastructure engineering, systems administration, networking, DevOps, or a related technical environment.

Strong hands-on Linux/RHEL experience, including system configuration, troubleshooting, patching, upgrades, and lifecycle support.

Experience with enterprise virtualization technologies such as VMware, oVirt/RHEV, Hyper-V, or similar platforms.

Working knowledge of Cisco networking, including switching, routing, VLANs, TCP/IP, DNS, and network troubleshooting.

Experience with OpenShift, Kubernetes, Docker, Podman, or similar container technologies.

Experience with infrastructure automation or scripting using Ansible, Bash, Python, PowerShell, or similar tools.

Ability to obtain and maintain a DoD Secret Security Clearance.

Current security-related certification such as Security+, CISSP, or equivalent, plus an OS/network-related certification such as Linux+, CCNA, or equivalent.

Strong computer hardware, operating system, networking, and enterprise software troubleshooting skills.

Preferred Qualifications:

Experience building and maintaining air-gapped or disconnected RHEL environments, including YUM/DNF/RPM repositories and internal container registries.

Experience deploying OpenShift or Kubernetes from bare-metal infrastructure.

Experience with VMware vSphere/vCenter, oVirt/RHEV, or Red Hat Satellite.

Familiarity with DISA STIGs, CAC, HBSS, vulnerability remediation, and DoD cybersecurity requirements.

Experience supporting DoD, federal government, command-and-control, laboratory, R&D, or other highly regulated environments.

Working knowledge of PostgreSQL, MySQL, Oracle, Apache HTTP Server, IIS, backup/recovery, and enterprise storage technologies.

Essential Duties:

Design, build, configure, and maintain Red Hat Enterprise Linux (RHEL) systems across physical and virtual environments.

Support isolated and air-gapped infrastructure, including internal Linux repositories, software/package mirrors, and private container registries.

Deploy, configure, and troubleshoot virtualization platforms such as VMware and oVirt/RHEV, including compute, networking, storage, provisioning, and lifecycle operations.

Build and maintain OpenShift/container infrastructure, including bare-metal deployments, cluster operations, upgrades, registries, and troubleshooting.

Support Cisco-based network infrastructure and troubleshoot connectivity across switches, routers, VLANs, servers, workstations, and related systems.

Develop scripts and automation to improve infrastructure deployment, configuration, maintenance, and reliability.

Administer and troubleshoot Linux and Windows systems, including patching, upgrades, migrations, vulnerability remediation, backup/recovery, and user support.

Support infrastructure technologies including LVM, iSCSI, SMB, NFS, Apache/IIS, relational databases, and source control systems such as SVN/Git.

Maintain secure and compliant infrastructure, including asset/patch tracking, system hardening, application authorization, and End-of-Life remediation.

Education:

Bachelor's degree in Computer Science, Information Technology, Engineering, or a related technical discipline.
